A meta‑analysis of the 20 crossover studies showed a statistically significant improvement in exercise capacity with dual‑chamber pacemakers compared with single‑chamber ventricular pacemakers ...

In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

A pacemaker may be useful for atrial fibrillation (AFib) involving a slow heart rate or other heart conduction disorders. However, doctors may recommend lifestyle changes to manage AFib before a ...

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published last week ...

A pacemaker can help your heart maintain a consistent rhythm. The procedure to insert a pacemaker typically involves a doctor making an incision in the skin that creates a “pocket” where the pacemaker ...

A meta‑analysis (based on the assumption that pacemaker syndrome does not occur in dual‑chamber pacing) of the 3 published RCTs showed a statistically significant reduction in the incidence of ...
